Huawei HarmonyOS 3.0 and OpenHarmony 3.1 are coming in September 2022

Huawei’s latest in-house operating systems — HarmonyOS 3.0 and OpenHarmony 3.1 — are rumoured to have a September 2022 release date.

According to a roadmap released by Changan Digital King, a Chinese leaker, Huawei already has plans to roll out the latest versions of its operating systems. 

Initially, a beta test version of HarmonyOS 3.0 should have been released in March 2022, but it now has a May release date due to delays. Also, the stable version was scheduled for July and has now been moved to September.

There are rumours that it will be launched along with the company’s next flagship smartphone, the Huawei Mate 50 series, but the device does not have a release date yet. Likely, the March delay may also see Huawei delay the release of any smartphone. says that the software will mostly feature development changes but very little will be different in its UI. Enthusiasts should expect improved performance and a better multi-device sharing mechanism because this is Huawei’s main goal.

Meanwhile, according to a developer review posted on the HarmonyOS homepage, its 3.0 update comes with API Version 7, which allows the development of ‘well-rounded’ apps.

“[It] introduces approximately 6,000 TypeScript and JavaScript APIs,” the makers claim. In addition, the software will feature the ArkUI, which uses something called ‘declarative syntax.’ The benefit of this is that it is closer to natural semantics, and it gives simple and intuitive code descriptions that developers can use easily.

“It offers simple UI information syntax, a wide range of UI components, and responsive live previewer, to boost your HarmonyOS application UI development efficiency by 30%. With just a single set of TypeScript and JavaScript APIs, you’ll be able to craft a smooth, vibrant UI experience between HarmonyOS devices,” it further explains.
